Photoshop CC 2015: Why am I unable to change the color of the background for documents with Artboards?

I just updated to 2015, I would like to change the color of the interface from white to black. The option that show when I right out of the art board. It gives me the option to change to black, dark gray, medium gray, default, or custom color.

Well, when I click on the color option, I tried all of them, it still didnt change the color on the interface.

I restarted the computer, I removed and added the CC2105, still doesnt fix the problem.
